Definitions

  • This invention relates generally to suction or vacuum cleaners, and more particularly to a novel and improved mounting structure for removably mounting disposable dust bags on such a cleaner.
  • the bags are only used once and are discarded when full of dirt and dust, they must be economical to produce and market. However, the bags must be sufficiently durable to permit them to be installed and removed without damage. They must also provide a connecting and sealing structure for con ⁇ necting the bag to the dirt-laden air discharge of the cleaner which is easily installed and which provides a reliable seal so that all of the dirt-laden air enters the filter bag.
  • Examples of disposable dust bag mounting systems are illustrated in United States Letters Patent Nos. 2,975,862; 3,150,405; 3,933,451; and 4,274,847.
  • the latter of such patents disclose a mounting structure providing a rigid cardboard or plastic collar and a plastic diaphragm secured to the body of the dust bag around the inlet opening therein.
  • the collar is provided with an opening having an enlarged portion which is sized to pass over a rib which extends around the end of the vacuum cleaner coupling.
  • the collar opening also provides a portion of reduced size which fits behind the rib when the collar is shifted laterally to the mounted position. Because of the shifting movement required, the collar must be relatively large. Also, because the diaphragm tends to lock the collar in the mounted position, the removal of the bag after use can be difficult.
  • the present invention provides a novel and improved mounting system for disposable dust bags for vacuum cleaners and the like.
  • the mounting system provides a low cost structure which is easily mounted and removed and which reliably provides a strong connection and a reliable seal.
  • the illustrated embodiment provides a vacuum cleaner connector having a generally cylindrical wall extending to an open end through which dirt-laden air is discharged by the vacuum cleaner fan. Peripherally spaced projections extend from the wall substantially adjacent to the open end thereof.
  • the dust bag is provided with a substantially rigid collar and an elasto eric diaphragm. The collar provides an opening therein having portions of reduced diameter sized to closely fit the outer surface of the connector wall and enlarged peripherally spaced portions sized to pass back and forth past the connector projections when the bag is in a mounting and removal position.
  • the collar is moved onto the connector, with the connector projections aligned with the enlarged portions of the collar opening, and is then rotated relative to the connector, causing the portions of reduced diameter to move in behind the connector projections to securely lock the collar on the connector.
  • Removal of the bag is accomplished by reversing the direction of rotation back to the mount ⁇ ing and removal position, after which the bag is removed.
  • the elastomeric diaphragm is provided with a centrally located opening having a diameter substan ⁇ tially smaller than the end of the coupling, and is adhesively secured to the collar entirely around the collar opening.
  • the collar is formed of two layers of stiff cardboard with a diaphragm sandwiched therebetween.
  • the diaphragm As the collar is pressed past the connector projections, the diaphragm is stretched over the pro ⁇ jections and the collar is rotated to the locked position.
  • the diaphragm When in the locked position, the diaphragm stretches outwardly along the back side of the projec ⁇ tions and extends forwardly over the projections and then inwardly along the forward face of the projec ⁇ tions.
  • This engagement between the diaphragm and the projections provides a tight fit and ensures that during use the collar remains in the locked position.
  • the opening in the diaphragm is initially sized so that the diaphragm extends inwardly along a substan ⁇ tial portion of the end of the connector wall with a tight fit.
  • the diaphragm provides an effective lip seal which prevents air pressure within the bag from causing leakage back along the exterior of the coupling.
  • the lip seal is also provided along any portions of the diaphragm which extend back along the outer cylindrical surface of the coupling so that a reliable seal is provided.
  • the bag itself is a vertically extending, elongated bag, and the inlet is spaced both from the upper and lower ends of the bag.
  • the dirt and dust collect within the bag it tends to collect within the lower portion below the inlet, leaving the upper portion of the bag substantially clear so that the air can pass out of the bag without developing a high back pressure which would substantially decrease the effectiveness of the cleaner.
  • the bag, with the dirt therein is removed and discarded so that a new, empty bag can be installed.
  • FIG. 1 is a schematic illustration of a vacuum cleaner with a disposable dust bag incorporat ⁇ ing this invention installed thereon;
  • FIG. 2 is a fragmentary, perspective view, illustrating the vacuum cleaner connector and the dust bag prior to the mounting of the dust bag;
  • FIG. 3 is a side elevation, partially in section, illustrating the connector and dust bag in the mounting and removal position
  • FIG. 3a is a fragmentary view, taken along line 3a - 3a of FIG. 3;
  • FIG. 4 is a side elevation, partially in section, illustrating the connector and dust bag in the fully mounted and locked position;
  • FIG.4a is a fragmentary section, taken along line 4a - 4a of FIG. 4.
  • FIG. 1 schematically illustrates a dis ⁇ posable dust bag and mounting system incorporating the present invention applied to a typical upright vacuum cleaner 10.
  • the vacuum cleaner 10 includes a motor and fan housing assembly 11.
  • Such cleaners are par ⁇ ticularly adapted for carpet and rug cleaning, and in many instances can be provided with various types of attachments for other types of cleaning operations.
  • dirt-laden air is discharged by the fan through a flexible hose 12 which extends upwardly from the housing assembly 11 within a cloth dust bag 13.
  • the dust bag 13 is con ⁇ nected at 14 to the housing assembly 11, and is sup ⁇ ported at its upper end from the handle 16 of the vacuum cleaner.
  • a disposable T ust bag 17 incorporat ⁇ ing the present invention is installed during use within the cloth dust bag 13.
  • the cloth dust bag 13 is provided with a zipper 18 which can be opened to provide access for the mounting and removal of the disposable dust bag 17.
  • Mounted on the upper end of the flexible hose 12 is a connector 19 which is connected to the disposable dust bag 17, as described in greater detail below, and through which dirt-laden air passes into the disposable dust bag 17.
  • the dust bag 17 is pro ⁇ vided with a mounting collar 21 which is removably mounted to the connector 19 so that all of the dirt- laden air from the cleaner enters the dust bag where the dirt is collected.
  • the connector 19 and the mounting collar of the disposable dust bag 17 is best illustrated in FIG. 2.
  • the connector 19, in the illustrated embodiment, is a molded plastic part providing a generally cylindrical inlet 22 connected by suitable means to the flexible hose 12.
  • the dirt- laden air enters the connector 19 through the inlet 22 of the connector 19 and is discharged through a gener ⁇ ally cylindrical outlet portion 23, which in the illustrated embodiment extends at right angles to the inlet 22.
  • the connector is provided with a pair of peripherally spaced mounting projections 26 and 27, which cooperate with the collar to securely mount the collar on the connector 19 when the dust bag 17 is mounted thereon.
  • the rearward walls 26a and 27a of the projections 16 and 27, respectively, extend radially and the forward walls are inclined.
  • the mounting collar 21, in the illustrated embodiment, includes two layers 31 and 32 of stiff, substantially rigid cardboard, which are laminated with adhesive to opposite sides of an elastomeric diaphragm 33.
  • the layer of cardboard 31 is also adhesively secured to the wall 34 of the disposable dust bag around the inlet 35 therein.
  • the dust bag is formed of an air-permeable paper material of the general type used in the past to form disposable dust bags for vacuum cleaners and the like, and is folded and seamed to define an elongated bag structure which defines a chamber 35a in which the dirt is collected.
  • the mounting collar 21 is located at a location spaced from the upper end 36 and the lower end 37 of the dust bag.
  • the dirt- laden air enters the bag from the connector 19 through the inlet 35, and the material forming the bag allows the air to pass out through the bag 17 and the cloth dust bag 13 to the environment while preventing the passage of the particles of dirt entrained within the air.
  • Such dirt tends to collect in the lower part of the bag and because the inlet is spaced from the upper end 36 of the bag, the upper portion of the bag re ⁇ mains relatively clear of collected dirt so that substantially free passage of the air occurs from the dust bag.
  • the dust bag In normal use, the dust bag is removed and discarded along with the dirt collected therein when the level of the dirt approaches the level of the inlet at the mounting collar.
  • the inlet By providing the inlet at a location below the upper end of the dust bag, the tendency for back pressure to be built up during the use of the cleaner is minimized and the efficiency of the cleaner is maintained until the bag is substan ⁇ tially filled to the level of the inlet provided by the collar 21.
  • the two layers 31 and 32 of the mounting collar 21 are formed with identical openings 41 therein and the diaphragm 33 is formed with a circular opening 42 which is substan ⁇ tially smaller than the openings 41 in the two collar layers 31 and 32.
  • the openings 41 are circular, except for two radially extending, enlarged portions 43 and 44, which are sized and positioned to clear the projections 26 and 27 when the collar is installed on and removed from the connector 19.
  • the projec ⁇ tions 26 and 27 are located on the top and bottom of the outlet portion of the connector 19 and the en ⁇ larged portions 43 and 44 are oriented with respect to the length of the bag at about 45 degrees.
  • the collar is oriented in an angled position in which the two enlarged portions 43 and 44 are aligned with the mounting projections 26 and 27, respectively, as best illustrated in FIGS. 3 and 3a. This is the mounting and removal position of the collar 21 with respect to the connector 19. In such position, the collar 21 is initially moved to the position illustrated in FIG. 3a, in which the diaphragm 33 engages the end 24 of the connector 19, and the circular portions 40 of the opening 41 in the two layers 31 and 32 align with and closely fit the exterior surface of the outlet portion 10
  • the mounting collar 21 is pushed from the full-line position illustrated in FIG. 3a to the phantom-line position, in which the collar extends behind the projections 26 and 27.
  • the collar is then rotated relative to the connector 19 to the fully mounted position illustrated in FIGS. 4 and 4a. In such position, the circular portions 40 of the collar are positioned behind the two projections 26 and 27, engaging the rearward walls 26a and 27a. Therefore, the collar is locked onto the connector.
  • the dia ⁇ phragm opening 42 is substantially smaller than the end of the connector 19 so that as the mounting collar is pressed over the end of the connector 19, the dia ⁇ phragm is stretched to the position illustrated in FIG. 4a, in which the diaphragm extends outwardly along the rearward sides 26a and 26b of the adjacent projections 26 and 27 and inwardly along the forward side of each projection.
  • the projection 26 is spaced back from the end 24 of the connector 19 and the projection 27 is substan ⁇ tially adjacent thereto. Consequently, the collar in its mounted position is inclined to some extent with respect to a plane perpendicular to the outlet portion 36.
  • the dia ⁇ phragm is stretched around the exterior wall of the outlet portion 23 and also extends in along the end 24 of the connector 19.
  • the diaphragm along that portion of the connector extends inwardly a small dis ⁇ tance beyond the end 24 but, adjacent to the pro ⁇ jection 26, the diaphragm engages the end 24 to a lesser extent.
  • this engagement between the diaphragm and the exterior wall of the connector 19 and along the end 24 thereof provides a lip seal which ensures that a fluidtight joint is provided between the disposable dust bag 17 and the connector. This ensures that all of the dirt-laden air passes into the disposable dust bag and that no leakage occurs.
  • the diaphragm provides a very snug mechanical contact with the end of the connector which frictionally maintains the dust bag in its mounted position and during the use of the cleaner.
  • the dust bag When the level of dirt collected in the dust bag reaches substantially to the level of the inlet provided by the mounting ring, the dust bag is rotated in the opposite direction to again bring the enlarged portions 43 and 44 into alignment with the associated projections 26 and 27 and the dust bag is easily removed from the connector for disposal. Subsequent ⁇ ly, a new, empty disposable dust bag is installed and cleaning operations can be continued.
  • the face of the collar is pro ⁇ vided with printed indicia 45 to indicate the proper position for the mounting of the dust bag on the collar and for its removal.
  • a low-cost, reliable structure which can be easily installed and removed by the user, and which ensures that a good seal is provided between the dust bag and the connector.

Abstract

Un sac à poussière jetable (17) pour aspirateurs comprend un collet de montage (21) monté de manière amovible sur le connecteur (19) de l'aspiration à travers lequel l'air chargé de poussière pénètre dans le sac (17). Le connecteur comprend une extrémité de sortie (24) généralement cylindrique et des protubérances (26, 27) espacées à sa périphérie qui font saillie sur sa surface externe. Le collet (21) comprend une ouverture (41) de dimensions adaptées à celles de l'extrémité de sortie (24) sur la plus grande partie de sa périphérie, des élargissements (43, 44) espacés sur sa périphérie qui passent par-dessus les protubérances (26, 27) lorsque le sac (17) est installé et enlevé, et un diaphragme élastomère (33) qui s'étend vers son intérieur et qui comprend une ouverture centrale (42) sensiblement plus petite que l'extrémité de sortie (24). Lorsque l'on installe le sac (17) sur le connecteur (19) ou qu'on l'en enlève, les élargissements (43, 44) s'alignent sur les protubérances (26, 27) et le collet (21) est sollicité sur le connecteur (19) jusqu'à être en position derrière les protubérances (26, 27). En mettant en rotation le collet (21) jusqu'à une position de montage où il enclenche le côté postérieur des protubérances (26, 27), on assujettit ensemble les deux éléments. Le diaphragme élastomère (33) s'adapte étroitement autour des projections (26, 27), formant un joint à lèvres avec le connecteur (19) qui évite des fuites en arrière de l'air chargé de poussière dans le connecteur (19).
